Yeah, waay wiggly at first, mine is still wiggly. Most dogs I think have a sweet spot where they love to be rubbed. Find that and I suspect Jude will hold still at least for a minute, ok shoot for 30 seconds.
Sounds like this is a bright dog. I find bright dogs are sensitive dogs, meaning not only are they sensitive to themselves but sensitive to others as well. If Jude left the litter at 8 weeks or longer, chances are good he has some social skills with other dogs. They play bite and also communicate with each other how hard they "can" bite.
I use the Yelping method with my dogs and it was the only thing that worked. I yelped like a school girl and found they understood. The rule here is no teeth to skin ever, even if they just brush their teeth next to the skin, the higher your voice inflection the greater the response. Yeah, it's not too manly, but it worked for me. The key here is everyone who get's mouthed has to yelp. Good luck on that one.
You might also consider using an article of your own clothing in Jude's bed. A well worn unwashed pillow case or an old t-shirt. Watch this one though should Jude decides it's a chew toy remove it as those pieces of cloth may get lodged should he ingest it.
I handle any new dog as much as possible and make physical contact even when they are a asleep on the floor or bed. I may simply rest my hand on a foot without wakening him or run my hand up his back and let him lay on it. I place a hand, elbow or arm next to his nose, so he can smell me in a relaxed state. Don't forget ears, tummy, cleaning the eyes and so on. You can't pet or handle him too much or mine would not have any hair left.
You're doing everything right and I suspect one day, you'll be amazed at what Jude will be. Just remember, puppies have small brains and thus less computing power and even a shorter attention span. Puppies are marathon not a sprint, enjoy the journey. I think he's the cutest guy on this board.
